SAN FRANCISCO -- Two of the greatest teams in Giants history will soon have the chance to test themselves against the cream of the crop in a new simulated tournament.

Major League Baseball and the makers of Out of the Park Baseball 21 will be staging MLB Dream Bracket 2: Dream Seasons beginning on Thursday. The MLB Dream Bracket 2 is a 64-team, best-of-seven simulation featuring two all-time teams from each of the 30 current Major League franchises (post-World War II), as well as three Negro Leagues teams and the 1994 Montreal Expos.

The 1954 New York Giants and the 2012 San Francisco Giants, both of which captured World Series titles for the franchise, will be featured in MLB Dream Bracket 2. The rosters for each of the 64 teams were selected by the MLB.com beat reporters in consultation with clubs.

The simulated competition, featuring many of the greatest teams in baseball history, is being produced by Out of the Park Baseball 21, MLB‘s most realistic strategy game (PC and Mac).
